The increasing economic activity reinforces the importance of climate change on a global scale. Together with the development of the economy and the increase in people's well-being, the emissions of greenhouse gases (GHG) which are released into the atmosphere as a result of human activities, also increase. Nitrous oxide (N2O) is one of the main greenhouse and ozone (O3) depleting gases. Seven percent of the anthropogenic greenhouse effect is nitrous oxide. From a molecular perspective, N2O has a 310-fold greater ...

EFFECT OF SOIL GRANULOMETRIC COMPOSITION AND MOISTURE ON THE FORMATION OF N2O ISOTOPES

(STEF92 Technology, 2023-12-15, Sindija Liepa, Dace Butenaite, Jovita Pilecka-Uļčugačeva, Kristaps Siltumens, Inga Grīnfelde)

Nitrous oxide (N2O) is one of important greenhouse gas (GHG) whose main sources are agricultural soils. N2O forms in soil as a result of microbial processes, reinforced by the use of nitrogen-containing fertilizers. This study will look at how the formation of N2O in soil is affected by soil moisture and soil granulometric composition. Soil N2O isotopes of ?15N? (central nitrogen position) and ?15N? (end nitrogen position) which could help to identify natural and anthropogenic sources of N2O emissions and the invo...

FORMATION OF N2O ISOTOPES IN AGRICULTURAL SOILS

(STEF92 Technology, 2023-10-01, Sindija Liepa, Dace Butenaite, Jovita Pilecka-Uļčugačeva, Kristaps Siltumens, Inga Grīnfelde)

Agricultural activity accounts for two-thirds of the total anthropogenic nitrogen oxide (N2O) emissions worldwide. Most of the N2O emissions from agricultural soils come from the use of inorganic fertilizers and/or manure. As agricultural activity intensifies worldwide, N2O emissions are currently increasing by 0.25% per year. In order to investigate the feedback of soil N2O emissions with changes in environmental conditions, an improved understanding based on the wider use of isotopic tracer methods is needed. Th...

GHG EMISSION VARIABILITY FROM SOIL IN CONVENTIONAL FARMING SYSTEM

(STEF92 Technology, 2023-12-15, Kristine Valujeva, Inga Grīnfelde, Jovita Pilecka-Uļčugačeva)

Show more

Reducing GHG emissions from soil is crucial for mitigating climate change, promoting sustainable agriculture, protecting ecosystems and biodiversity, ensuring food security, and improving public health. The effectiveness of GHG mitigating strategies may vary depending on local conditions, soil type, and agricultural practices. It is recognized that conventional farming practices may lead to increased GHG emissions compared to more sustainable farming systems. Therefore, the aim of this study is to research the GHG...

INTERACTION BETWEEN METHANE AND CARBON DIOXIDE EMISSIONS USING METHANE-REDUCING BIOCOVER

(STEF92 Technology, 2023-12-15, Kristaps Siltumens, Inga Grīnfelde, Juris Burlakovs, Sindija Liepa, Jovita Pilecka-Uļčugačeva)

Decomposition of solid waste in landfills causes global air pollution with methane, the most dangerous of the greenhouse gases. The emission potential of this gas is 28-36 times greater than that of CO2. With the help of methane-reducing Biocover, can find a solution to this problem. In this study, a biocover was developed in the laboratory to reduce methane emissions. When measuring the methane emissions of this biocover, data on the amount of carbon dioxide emissions were also obtained in parallel. The purpose o...

Landfills of municipal waste are important sources of methane emissions. The surface of the landfill area is the interface between the waste layer and the atmosphere. By creating a biocover cover layer, it is possible to reduce methane emissions that would refer to air quality. This innovative biocover technology aims to curtail methane emissions from various sources. The research delves into the effectiveness of this biocover in not only mitigating methane emissions but also its potential influence on nitrous oxi...

Global warming caused by greenhouse gas (GHG) emissions is a global problem. Solid municipal waste landfills are the third largest source of artificial methane emissions. Methane is one of the greenhouse gases contributing to global warming. The net zero emissions target was set to strike a balance between emissions and anthropogenic GHG disposal by 2050. Methane emissions from active or closed landfills may be reduced by methane oxidation, which is developed as a coating over these landfills. Methane (CH4) is an ...

Every year, cities are becoming more populated and urban traffic more intense. Urban air quality is deteriorating and causes for pollution are being sought and solutions to improve the quality of life in urban areas. Atmospheric deposits, vehicles, traffic and de-icing products are the main sources of snow pollution in cities. Snow, located near roads and streets with intense traffic, is a very useful tool for identifying the risks of traffic-related metals in the environment. In many countries, in winter, they us...

In order to reduce the impact of agricultural activity on global warming and promote sustainable land management, it is necessary to implement management practices that reduce GHG emissions from agriculture. Conventional soil tillage produces favorable conditions for the growth of seeds and plants, but it is an energy and labor-intensive method that alters the soil to an unfavorable condition, while reduced soil tillage decrease the use of energy resources, GHG emissions from the soils, and improves the soil quali...

The number of transport units in cities is increasing every year. This trend contributes to air pollution problems in many rapidly urbanizing countries. Various heavy metals and other chemical elements, including aluminum, have been related to air quality degradation. Poor air quality affects people, especially young children, the elderly, and people with chronic illnesses, causing health problems and aggravating existing problems. The aim of the research is to find out which parts of the city of Jelgava have the ...
